RUG-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 272,697, dated February 20, 1883.

Application filed December 13, 18H. (No model.)

To all whom it may concern:

Be it known that 1,()R1soN HUFF, of Goodwins Mills,u the county ot' York and State of Maine, have invented a new and useful Improvement in Rug-Making Machines, ot' which the followingis a full, clear, and exact description.

My improvements relate to machines for the manufacture of rugs in which a piled surface of yarn or Worsted is formed upon a backing of canvas or similar material; and the invention consists in the mechanism for forming `the loops or stitches, and for changing the yarn so as to vary the colors, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specication, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a vertical longitudinal section of the machine. Fig. 2 is a partial inverted plan of the bed. Fig. 3 is a horizontal section on line x :v of Fig. 1. Fig. 4 is a view of the machine in section transversely. Fig. 5 is an elevation of the looping hook and carrier. Fig. 6 is a side view of the feed-bar. Fig. 7 shows the lifting-cam of the feed-bar. Fig. 8 shows the pitman-connection of the needle-driver. Figs. 9, l0, and 1l are details views; and Fig. 12 represents a piece of fabric having a series of loops formed thereon.

A is the hed,supported by pillars c a at its ends, and formed with avneedleslot, c2, and with a hollow arm, B, at its upper side, in which the main shaft C is carried.

b is a crank-wheel ou the" shaft, by means .of which the latter may be turned.

On the end of arm B is a hollow head, B', carrying the feed and hooking mechanism, as next described.

c is a guide-bar, fitted for vertical movement in head B.

d is a bar pivoted by a pin, c', at the lower end of bar c, and provided at its lower end with a hook, d'.

c is a cam-disk on the end of shaft C, having its edge engaged by a grocved or hook-shaped fiange on the upperend of bar d, by which the cam vibraies the hook-bar in a plane at right angles to the feed.

fis the feed-bar, also pivoted by a pin, e', o the lower end of bar c.

g is a cam on shaft C, working in a slot of feed-barf. (see Figs. 1 and 6,) for vibrating the barlateraliy on its pivote', and g" is a second cam on the shaft, (shown in Figs. l and 7,) taking beneath an arm,f, on the end of bat-j', to raise the bar, and consequently serving to raise the bar c and its attached parts. These cams give to the barf the four motions required for the feed. the hook-bar d part-.thing ofthe rising and falling motions, besides having its separate vibrating movement.

On the vibrating har d is pivoted a hook, h, extending at the side ot' the feed-bar opposite to hook d', and engaged at its upper end by a spring, h', attached on bar d, the spring tending to move the hook h toward hook d', the movement being limited bya pin, 92,011 har d.

To the lower endot' feed-barfcurved plates are attached to form a hollow foot, t, one side ot which has a slot, t", for the hook d to enter, while the other side has a small aperture for the end of hook It. A bent afan-f2, attached on barf, extends in front ot'- the ioot 1'..

The needle and other mechanism are mainly located beneath bed A, and are as follows:

D is a rocking lever, pivoted at 7c', and operated by a pitman, k, extending from the rear end' ofthe lever .upward to and connecting by a yoke (shown in Fig. 8) with a crank, l, on shaft C.

fm is a rod pivoted to the forward end of lever D, and extending upward through a fixed guide, l'.

m is a collar on rod m, formed with a horizontal slot, for engaging the needle-holders.

The lever D is pivoted on a second lever, E, which is pivoted by its T end in the back pillar c, while its forward end extends to near the opposite pillar a, where a horizont-al rockshaftnt, sustained in suitablebearings, engages by a crank-arm, u', a slot,o, formed in the end of lever E. A rod, o', from a second arm,`u2, on shaft n passes to and is connected to a vertical crank-shaft,p, that extends above bed A, where it is provided with a handle, p. A third arm, n3, on shaft n connects by a piu and slot with an arm, q, pivoted on guide l', for

purposes hereinafter described. A rod, fr, from an arm on shaft p passes to and is connected to a turning-plate, q', attached beneath Vbed. A, (see Fig. 2,) which plate has pins r'r, taking between two shear-blades, ss, that IOO are pivoted upon the bed A in position for cutting the yarn at the needle-slot a2. The shears are opened by a springs', (see Fig. 13,) and closed by the movement of plate q. There is also Xed on shaft 1) an arm, p2, that is moved when the shaft is partially rotated, as hereinafter described, beneath a projection or flange, 7a2, on the pitman k, (see Fig. 11,) so as to arrest the downward movement of the pitman while the needles are being changed. Through the connections, as described, the movement of shaft p, by means of handle 19', a quarter/turn (more or less) carries lever E down, and with it the lever D. It also moves the plate g', thereby closing shears s,- and, further, it moves the arm q out of one of the notches, u2, hereinafter referred to, so as to allow the shifting of the needle-frame.

F is a vertical post extending from the top of arm B down through the bed A, and carrying at its lower end a bobbin-holder, Gr, and needle-frame H.

On the upper end ot' the post F is fixed al quadrant, t, having notches in its outer end, corresponding in number with the bobbins. and engaged bya spring-actedretaining-pin, t', mounted in a lug on arm B2 The bobbin-holder G is a plate hung to swing loosely on post F, and provided with pins t2, that carry the bobbins, as shown.

'lhe needle-frame H (shown most clearly in Fig. 3) is fixed on post4 F by the setscrew shown in Fig. 1, or other suitable means, to swing with it, and is provided at its outer end with rails u u, curved in the arc of a circle described from the post F as a center, the upper rail resting for support on a plate, a', fixed on the guide Z.

The needle carriers or holders consist of rods o, extending through the rails a, so that the rails serve as guides in which the rods slide. The needles o' are set in recesses in the upper ends of rods e, and are held by setscrews e?, (shown in Fig. 4,) countersunk, in order that the said rod u may slide through the rail u. On the lower ends of rods t are flanges or projections w, for engaging the slotted collar m of rod m.

Ou the needle-holders t are attached guidepins w', extending through the lower rail, u, to prevent any turning movement. The lower rail, u, as shown most clearly in Fig. 4. has notches or slots a2 between the needle-holders, for engagement, by the inner end of arm q, before mentioned,when the parts are in operative position, so as to hold the carrier H securely. The upper rail is fitted with a plate, to2, (shown in Figs. 1 and 3,) apertured to serve as a guide for the yarns, which pass from the several bobbins through plate to2 to the eyes ot needles v'.

In the operative position of the parts, as shown in Fig. 1, the lever E is in a raised position, and needle-lever D being also raised, the needle-holder that is engaged with the reciprocating rod m is sustained slightly above the holder not in use. The change from one yarn to another is made during the stoppage ofthe machine as follows: The handle of shaft p is first turned by hand to the left, shaft n is thereby turned through the connections hereinbefore described, and by the connections of the shaft n to the lever E the lever is carried down. The lever D moving down with the lever E, the previously-used holder is brought down from the slightly-elevated position shown in Fig. 1 into line with the other holders. The movement of shaft a, before described, also turns the arm q out of the notch u2 in the rail a. At the same time the shaft p, acting through the rod i", gives a partial revolution tothe plate q', and the pins r on the plate moving the shears s, the yarn is cut. Simultaneously with these movements the arm p2 on the shaftp is carried beneath the projection kon the rod k, and thereby prevents any downward movement of the rod while the needles are being adjusted. The carrier H can then be moved by taking hold of quadrant t, after pulling back the pin t', and either of the needle-holders can be brought into connection with the'collar fm', which being done the pin t is released to hold the parts. The shaftp is then to be turned back to cause the parts to resume the operative position shown in Fig. 1.

In the operation of the machine, after the foundation fabric is passed underneath the presser-foot t, the yarn is carried by the needle through the slot a2 upward through the fabric and into the hollow foot rlhe hook d is carried by the action of the cam e through the aperture i in the side ot' the presser-foot and catches the loop of yarn, as shown in Fig. 9. The presser-foot is then moved forward by the action of the cam g upon the bar f, while the loop is held by the hook d', and the needle at the same time drops, thus drawing the yarn out to the length required for the stitch. The feed-Darf and its attached parts then rise, and the presser-foot moves backward, the hook d moves outward, and at the same time the hook It is carried into the presser-foot i, as shown in Fig. 10, to engage with the loop as it is released from the hook d. The hook It, being of flexible material, bends to accommodate the forward movement of the presser-foot, at which time the two hooks occupy the relative position shown in Fig. 10, after which the presser-foot moves back, the hook d withdraws, and hook li enters in order to hold the old loop while a new one is being` formed. It will be understood that hook h, being carried on the bar d, will always maintain its distance from bool; d', and the alternate in and out movement ofthe two hooks is thus insured. In this manner a row of loops or stitches is formed across the face of the foundation fabric, as shown in Fig. 12. The fabric is then to be turned around and a second row formed, and so on to the extent required. In this manner, by changing the yarn, striped and other gured rugs can be manufactured.
